Left-hand spindle for securing buffs with a set-screw.
This left-hand tapered spindle is designed for the left side of a 6, inch polishing motor, ensuring the threads tighten in the direction of rotation. It features a secure 5/8, inch internal diameter with a robust set screw for a permanent, vibration-free attachment to the motor shaft. The precision machining ensures 100, percent concentricity, which is vital for preventing the wheel "chatter" that can ruin a fine jewelry finish. This is a professional-grade part built for the high-torque demands of an industrial polishing bench.
This is a replacement set-screw tapered left-hand mandrel for a 5/8" round motor shaft with one flat side for Split Lap Motors.
